Killed a wicked fast 4 wheel drive truck

Last week I was going home on a very curvey road and this huge truck that was raised high off the ground ran up on my bumper. He started pumping the gas and that thing sounded wicked. I was like well sounds good but this is curves and that truck is wayyyy to heavy. So I bump it around 65 through some 35 mph curves. That dang truck hang in there great. I mean I ran off and left him but was very surprised how that truck took the curves. i slowed down in a straight and let him catch up. Hit 120 but couldnt leave the truck out of site. I nailed some good curves at 85 plus and the truck still hung in there. Wished I could have talked with the guy and see how much hp he had and the setup underneath.
